Sifr is a mobile-first, AI-powered IDE that lets you work on your real codebases from your phone.

KEY FEATURES • AI-Powered Development Tell the AI what to build in natural language. It reads your codebase, plans the implementation, writes the code, and waits for your approval. • Work on Real Projects Connect your GitHub repositories and work on actual codebases. Not toy apps — your production code. • Full Git Workflow View status, review diffs, stage changes, commit, and push — all from your phone. Ship code without opening your laptop. • Permission Control Choose how much freedom the AI has. Safe mode for exploration, Balanced for everyday work, or Autonomous for power users. • Multi-Model Support Access Claude, GPT, Gemini, and more through OpenRouter. Pick the best model for each task, or let Sifr auto-select. • Transparent Pricing Pay for what you use. See costs in real-time. No surprise bills. PERFECT FOR • Quick bug fixes while commuting • Code review on the go • Shipping features from anywhere • On-call incident response • Learning and experimentation FROM ZERO, EVERYTHING IS BUILT Sifr (صفر) is the Arabic word for "zero" — the origin of the word "cipher" and the concept of zero in mathematics.

Send a prompt to Claude Code, opencode or Oh My Pi from your phone, pocket it, and watch the turn finish on your Lock Screen. Approve the risky command, answer the agent's question, read every diff — from anywhere on your own Tailscale network. WHAT YOU NEED A Mac or Linux machine on your tailnet (Tailscale is free for personal use) running one of your agents: opencode, Claude Code through the open-source claude-bridge, or Oh My Pi through the open-source omp-bridge. Set-up is three verified steps, and a built-in demo lets you try every screen before you wire anything. THE TURN, LIVE ON YOUR LOCK SCREEN • A Live Activity per conversation: what it is doing, for how long, and how many tools it has run. • An approval request alerts you; a finished turn lingers with its outcome. Tap to land in the exact chat. • Updates arrive by push while the app is suspended. A NATIVE TRANSCRIPT, NOT A TERMINAL • Streaming text written at the model's own speed, with thinking and tool runs folded into readable groups. • Diffs, commands and their real output inline; syntax-highlighted code with byte-exact copy. • Allow once, always, or deny — without leaving the chat. Agent questions become tappable cards. • Queue the next message while a turn runs, edit it before it goes, or stop the turn on the server. • Every picture the agent hands you, in a gallery you can zoom, save or share. EVERY MACHINE ON ONE BOARD • All your servers' conversations in one list, live status first, grouped by project. • Read the repository before you trust the change: branch, staged, changed, untracked, and the diff of any file. • Subagents dock inside the turn that spawned them; a compaction is drawn as a seam with what it kept. • Slash commands from the server's own catalog, per-message model and reasoning effort, forking. KNOW WHAT IT COSTS • Every conversation priced, every month totalled across machines — by model, project and tool. • Plan limits and quotas for Claude, Grok, Ollama Cloud, DeepSeek and more, on Home and in a widget. YOURS, END TO END • Point-to-point over your tailnet. No relay servers, no account, no analytics, nobody reading your code. • Programmatic UIKit, Swift 6, Liquid Glass on iOS 26. Dark mode, Dynamic Type, haptics. • Open source under GPL-3.0 — the app, the engine, and both bridges. FREE, WITH AN HONEST PRO The free app is the complete core: one server, full chat, approvals, attachments, models, forking, and Live Activities. Tailscode Pro is a one-time purchase, no subscription: multiple saved servers, concurrent Live Activities, and a supporter badge. Tailscode is independent open-source software: not affiliated with or endorsed by Anthropic, Tailscale Inc., the opencode project or Oh My Pi.
